中文编码出现问题

Hello @Songyun_Zhang8775!

I hope you are doing well, and thanks for reaching out.

++ In addition to what our community product expert has shared, you need to identify which fonts the PDF is actually using (and whether they’re embedded) so you can install any missing ones on your system. 

Check via Document Properties

• In Acrobat Pro, open your PDF and go to Menu→ Properties, then click the Fonts tab.

• You’ll see every font the PDF references, and whether it’s Embedded or Embedded Subset.

• Note any Chinese fonts listed (e.g., “SimSun,” “MS Song,” “PingFang-SC”).

Generate a Detailed Font Report with Preflight

• Go to All Tools → Print Production → Preflight.

• In the dialog, search for “List all fonts” or use the PDF Analysis profile.

• Run it to produce a report showing font names, encodings, and embedding status.

Install Missing Font Files

• Once you know the exact font names, download the corresponding .ttf or .otf files from a trusted source (e.g., your font vendor or Adobe Fonts).

• Install them on your operating system:

  • Windows: Right-click the font file → Install.

  • macOS: Double-click the font file in Font Book → Install Font.

Please ensure you have the latest version of Acrobat installed on the machine: 25.001.20474 (Win) | 25.001.20476 (Mac), Apr 28, 2025. Check for any pending updates from the Menu > help > check for updates, install the updates, restart the app and the machine, and try again.

See these articles to know more about PDF fonts, embedding fonts in a PDF, and using the Preflight tool for fix-ups:

If you still see encoding issues after installing the fonts, ensure the PDF export from the source application correctly embeds the fonts (or ask the PDF’s creator to re-export with full font embedding enabled).

I hope this helps.

Thanks,

Anand Sri.
